This link will take you to all SF Homes in Wall under 300K (There were only 5)
If going a bit further south could be a consideration, there are some properties under 200K. The following link is only helpful if towns south of wall, or in Ocean County will meet your needs.
There weren't any condos in Wall, but other towns might provide that as an alternative.
Let us know if we can help further.
